In 2016 the fall armyworm, a major pest in the Americas, was found in Africa for the first time. Since then it has rapidly spread across much of sub-Saharan Africa. The caterpillar feeds on more than 80 different plants, but maize is its preferred host, the most widely grown crop in Africa and a staple for half the continent. In the context of Africa’s climate, the insect is now likely to build permanent and significant populations in West, Central and Southern Africa, and spread to other regions when temperatures are favourable, posing a major threat to food security.
The fall armyworm is still invading regions in Africa. Since 2016 this worm has been spreading across sub-Saharan Africa and has been officially identified in 11 countries. Roger Day from the Centre for Agriculture and Biosciences International (CABI) elaborates on its dangers in this blog and provides recommendations for governments and farmers.Continue reading →
The fall armyworm, Spodoptera frugiperda, is making headlines worldwide for all the wrong reasons. The caterpillar crop pest, native to the Americas, was reported in Africa for the first time last year and is now rapidly marching across the continent. It is a voracious pest of maize and other staple crops and has already destroyed tens of thousands of hectares of farmland. As such, it risks devastating smallholder livelihoods throughout Africa. Given that CABI scientists predict it could reach Europe and Asia in a matter of years, it looks set to quickly become a global problem.
The case for action against fall armyworm is overwhelming. On the ground, CABI will support national extension services to help farmers identify the pest quickly and accurately, contribute to awareness-raising and conduct studies to work out the best ways to control it that are not overly dependent on insecticides. Alongside these efforts, CABI also has a range of freely-available materials to help people understand and manage fall armyworm. Continue reading →
